BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a clothing accessory, and more particularly, to a tensioning device that draws clothing straps, such as brassiere straps, together to keep them from inadvertently slipping down over the wearer's shoulders and, in the case of brassiere straps, imparts an upward lift to the brassiere cups.

2. Description of the Prior Art

Clothing having straps, such as tank tops and brassieres that provide women support, are well known in the art. Although common, conventional straps can be uncomfortable and unreliable in providing support. Comfort and reliability are typically compromised when the straps inadvertently slip down or off the shoulders. Straps often slip down the shoulders when they lose tension due to stretching and loosening of the elastic straps over time, affecting the comfort, appearance and support of the brassiere or garment. Furthermore, with regard to brassieres, women are constantly searching for products such as push-up type brassieres, which, in addition to providing the usual support, offer enhanced upward lift to the breasts via the brassiere cups.

If a device existed that could prevent and/or limit inadvertent movement and slipping of straps by maintaining tension in the straps it would be well received. Furthermore, it would be desirable to provide such a device that, in addition to preventing such slipping of the straps, provided enhanced upward lift to the brassiere cups in order to impart corresponding upward lift to the wearer's breasts. The present invention addresses these unfulfilled needs in the prior art by providing an accessory that maintains tension in clothing straps, even after they have lost some degree of elasticity, preventing them from slipping, and providing the aforementioned enhanced upward lift.

SUMMARY OF THE INVENTION

The present invention is generally directed to a clothing strap tensioning device configured to draw a pair of vertically disposed clothing straps toward each other in a manner increasing the tension of the straps.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Shown throughout the figures, the present invention is generally directed to clothing strap tensioning devices particularly configured for engaging a pair of spaced-apart vertically disposed clothing straps, and particularly brassiere straps, such that the straps are drawn toward each other medially. The tensioning devices function to prevent the inadvertent slipping of the straps down over the shoulders. Furthermore, when applied to brassiere straps, the tensioning devices further function to impart an upward lift to brassiere cups attached to the straps.

Referring initially to FIGS. 1 and 2, a conventional brassiere in accordance with the prior art, shown generally as reference numeral 10, includes a pair of spaced-apart vertically oriented straps 12, 14 each adjoined at one end adjacent to the back of a wearer by a horizontally oriented portion 16, and terminating at an opposite end adjacent the front of the wearer at a cup portion 18. As best illustrated in FIG. 2, this conventional prior art brassiere structure provides only limited support to the breasts of the wearer. Over time, as the elasticity of the straps 12, 14 is reduced, support is even further diminished. Furthermore, the resulting reduced tension in the straps commonly leads to slipping of the straps down the shoulders of the wearer.

Referring now to FIGS. 3A, 4 and 5, a tensioning device 20 is shown in accordance with a first general embodiment of the present invention. The tensioning device 20 includes a generally elongated elastic member 22, preferably having a symmetric geometry to impart substantially equal tension to each strap, and comprising a middle portion 24 adjoining a left end portion 26 and a right end portion 28. The elastic member has a shape defined by left edge 21, right edge 23, lower edge 25 and upper edge 27. A variety of elastic member 22 geometries are contemplated, including a generally rectangular-shaped elastic member. However, for reasons that will become apparent, the general geometry illustrated in FIGS. 3A, 4 and 5 is preferred. In particular, it is preferred that the elastic member 22 have a geometry wherein the left and right end portions 26, 28 of the elastic member project upwardly in a direction away from the middle portion. Furthermore, it is preferred that the elastic member 22 has an increased transverse width along corresponding segments of the left and right end portions, 26 and 28, adjacent to the middle portion 24. As used herein, the term “transverse width” is intended to define the distance between points on the lower and upper edges, 25 and 27, along any vertical section through member 22.

Fastening means are provided for enabling releasable attachment of the left- and right-end portions, 26 and 28, to each other to form a continuous loop, or band, about the straps 12, 14, as illustrated in FIG. 4. As shown in FIGS. 3A, 4 and 5, in one aspect of the invention releasable attachment is achieved using conventional mechanical snaps 30, 32. Preferably a single snap 32 is integrated into one of the end portions (in this case right end portion 28), and a plurality of mating snaps 30 are provided integrated into the other end portion (in this case left end portion 26) in spaced-apart relationship, enabling the user to vary the degree of tension imparted by the tensioning device 20 to the straps 12, 14. As will be apparent to those skilled in the art, various alternate means of attachment are possible. For example, releasable attachment may be achieved by integrating one half of a hook-and-loop, or hook-and-pile, type fastening system (not shown) into the left end portion 26 of the elastic member 22, and integrating the other half of the hook-and-loop type fastening system into the right end portion 28. Metallic and plastic snap-fits, clasps, magnets, buttons and any other known releasable attachment mechanisms that can be employed to enable tension adjustment are also contemplated. Furthermore, tension adjustment can be accomplished by incorporating a conventional slide component through which the elastic member 22 extends and which cooperates with the elastic member to enable length adjustment thereof.

Referring now to FIGS. 3A, 4, 5 and 6, and particularly to FIG. 6, when the elastic member 22 is engaged around the straps 12, 14 and closed, the middle portion 24 of the elastic member is positioned adjacent to the wearer's back and engages the inner surface of the straps 12, 14, while the left- and right-end portions, 26 and 28, of the elastic member 22 are positioned along and, at least partially engage, the outer surface of the straps. Accordingly, the portions of the elastic member 22 having the increased transverse width are positioned adjacent to, and frictionally engage, the outer edges of the straps. The engagement of the aforementioned wider portions of the member 22 with the outer edges of the straps 12, 14 functions to stabilize the straps in order to reduce the occurrence of strap twisting. As best shown in FIG. 7, upon application of the tensioning device 20 to a conventional brassiere, the increased tension to the straps acts to impart an upward lift to the brassiere cups, providing the desired pushing up of the breasts desired by women.

Referring now to FIGS. 8-9, a tensioning mechanism is shown in accordance with a second general embodiment of the present invention. The tensioning mechanism includes a first elastic member 34 having a portion 36 permanently stitched, or otherwise secured, to the left brassiere strap 12, and a second elastic member 40 having a portion 42 secured in a similar fashion to the right brassiere strap 14. Attachment means 38, 44 are preferably integrated into the non-stitched flap portions of the elastic members to enable and facilitate releasable attachment of the elastic members 34, 40 to each other such that the vertically oriented straps 12, 14 of the brassiere are drawn toward each other to impart tension to the straps, and corresponding upward lift to the brassiere cups.

As best shown in FIG. 8, the preferred means of attachment is by a hook-and-loop type fastening system. In particular, one half of a hook-and-loop, or hook-and-pile, type fastening system 38 is integrated into the left elastic member 34 attached to the left vertical strap 12, and the other half of the hook-and-loop type fastening system 44 is integrated into the right elastic member 40 attached to the right vertical strap 14. In this manner, the degree of tension imparted to the straps can be varied by adjusting the degree of overlap of the elastic members 34, 40 during attachment. As will be apparent to those skilled in the art, various alternate means of attachment are possible. For example, releasable attachment may be achieved by conventional mechanical snaps, metallic and plastic snap-fit assemblies, clasps, magnets, buttons and any other known releasable attachment mechanisms that can be employed to enable tension adjustment by the wearer.

Referring now to FIG. 10, a tensioning device is shown in accordance with a third general embodiment of the present invention. In this embodiment of the invention, the device is comprised of a semi-rigid or rigid unitary member, shown generally as reference numeral 46. The tensioning member 46 has a geometry generally defined by planar rear wall portion 48, and left and right planar front wall portions, 50 and 52, respectively, adjoined by semi-circular sidewall portions. The front wall portions 50, 52 are disposed in a common plane slightly offset from and parallel to the rear wall portion 48. The left and right front wall portions terminate at respective edges defining a strap-receiving opening 54 therebetween. The rear, front and side wall portions together define a strap retaining slot 56 sized and shaped for simultaneously retaining the pair of clothing straps in a tensioned condition while preventing twisting of the straps. The slot 56 is the open-ended opening for fitting a strap when in use. As shown in FIG. 10, this slot 56 is distinct from a slot used for a button fastener or a snap-fit.

Referring now to FIG. 3B, a tensioning device 20 is shown in accordance with another embodiment of the present invention. The tensioning device 20 includes a generally elongated elastic member 22, preferably having a symmetric geometry to impart substantially equal tension to each strap, and comprising a middle portion 24 adjoining a left end portion 26 and a right end portion 28. A generally rectangular-shaped elastic member 22 may be used as shown in FIG. 3A.

Fastening means 58 are provided for enabling releasable attachment of the left- and right-end portions, 26 and 28, to each other to form a continuous loop, or band, about straps 12, 14, as illustrated in FIG. 4. As shown in FIG. 3B in one aspect of the invention releasable attachment is achieved using a conventional button 60 and buttonhole 62 mechanism. Preferably a single button 60 is integrated into one of the end portions (in this case left end portion 26), and one or more complementary button holes 62 are provided in the other end portion (in this case right end portion 28) in spaced-apart relationship, enabling the user to vary the degree of tension imparted by the tensioning device 20 to the straps 12, 14. As will be apparent to those skilled in the art, various alternate means of attachment are possible. Furthermore, as described in more detail below, tension adjustment can be accomplished by incorporating a conventional slide component through which the elastic member 22 extends and which cooperates with the elastic member to enable length adjustment thereof.

Referring now to FIG. 3C-3E, a tensioning device 20 is shown in accordance with yet another embodiment of the present invention. The tensioning device 20 includes a generally elongated elastic member, preferably having a symmetric geometry to impart substantially equal tension to each strap, and comprising a middle portion adjoining a left end portion 26 and a right end portion 28. A generally rectangular-shaped elastic member may be used as shown in FIG. 3C-3E.

Fastening means 58 are provided for enabling releasable attachment of the left- and right-end portions, 26 and 28, to each other to form a continuous loop, or band, about straps 12, 14, as illustrated in FIG. 4. As shown in FIG. 3C-3E in one aspect of the invention releasable attachment is achieved using a snap clip mechanism. These fastening means may have a generally rectangular shape. Preferably a first snap clip 64 is integrated into one of the end portions (in this case left end portion 26), and a complementary second snap clip 66 is provided in the other end portion (in this case right end portion 28) in spaced-apart relationship, enabling the user to vary the degree of tension imparted by the tensioning device 20 to the straps 12, 14. As shown in FIGS. 3C-3E, the first snap clip and the second snap clip may be of complementary shape so that they may complementarily fit one another. Also, the first snap clip and the second snap clip may be the same shape and in complementary orientation. For example each snap clip may include an indentation 68,70 or slot whereby the snap clips 64,66 may be inserted within each other. The snap clips also may include perforations 72,74 and extension 76,78 which are also complementary. Thus the extension 76 of the first snap clip 64 fits into the perforation 74 of the second clip 66, and the extension 78 of the second clip 66 fits in the perforation 72 of the first clip 64. Additionally, the outer portion 80,82 of each snap clip 64,66 may have a surface offset from but parallel to the inner portion 84,86 of each snap clip 64,66 so that when the snap clips fit together the snap clips 64,66 the thickness of the outer surface of the first clip and the inner surface of the second clip is approximately the same as the thicknesses of the inner surface of the first clip and the outer surface of the second clip, thereby forming a substantially flat rectangular shape.

As will be apparent to those skilled in the art, various alternate means of attachment are also possible. Furthermore, tension adjustment can be accomplished by incorporating a conventional slide component 88 through which the elastic member extends and which cooperates with the elastic member to enable length adjustment thereof. The slide component 88 may be attached to an end of the elastic member and be able to slide along the length of the elastic member so that the length of the device may be adjusted by sliding the slide component along the length of the elastic member.

Since many modifications, variations, and changes in detail can be made to the described preferred embodiments of the invention, it is intended that all matters in the foregoing description and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense. Thus, the scope of the invention should be determined by the appended claims and their legal equivalence.
